Agents for Job Execution and Communication Tasks
================================================
Agents collect informations and transfer them e.g. to a loops server.

This package does not depend on zope or the other loops packages
but represents a standalone application.
But we need a reactor for working with Twisted; in order not to block
testing when running the reactor we use reactor.iterate() calls
wrapped in a ``tester`` object.
>>> from cybertools.agent.tests import tester
Crawler
============
The agent uses Twisted's cooperative multitasking model.
Crawler is the base class for all derived Crawlers like the filesystem crawler
and the mailcrawler. The SampleCrawler returns a deferred that already had a
callback being called, so it will return at once.
Returns a deferred that must be supplied with a callback method (and in
most cases also an errback method).
>>> from cybertools.agent.crawl.base import SampleCrawler
>>> from twisted.internet import defer
>>> crawler = SampleCrawler()
>>> deferred = crawler.collect()
SampleCrawler is collecting.
